Weed suppression by forage legumes in silvopastoral systems and its effect on soil chemical characteristics

Even when considered a modern cultivation system, silvopastoral systems can be rapidly degraded if some cares, mainly related to weed control, are not observed at the early stages of establishment this system. The present work had objective evaluating use forage legumes on suppression and initial development Teak (Tectona grandis) implementing Four legume species were used, namely: pinto peanut (Arachis pintoi), Brazilian stylos (Stylosanthes guianensis), cowpea (Vigna unguiculata) pigeon pea (Cajanus cajan), which compared with three weeding regimes: (i) mowing, (ii) hand weeding, (iii) zero (unweeded plot). experiment was laid out in randomized complete-block design four replications. Each experimental plot consisted length corresponding plants by meters width. Weed assessments carried end annual growing period, represented high rainfall season region. identified quantified. dry matter produced found determined. assessed measuring height, stem diameter neck breast height 2-year period. Pinto put little competitive pressure weeds, although they largest quantities organic available nitrogen soil did interfere growth variables teak component.
